Description

Technical Field

[0001] This utility model relates to the field of carton printing technology, specifically to a carton printing paper feeding device that allows for wrench-free adjustment of the paper feeding rollers. Background Technology

[0002] Carton printing machines, through high-speed printing and die-cutting functions, enable the printing and forming process of cartons to be completed quickly, greatly improving the efficiency of logistics packaging. Compared with traditional manual printing methods, carton printing machines can significantly reduce manual intervention, lower labor costs, and also reduce product quality problems caused by human factors. The printed patterns, text, and logos are clear and neat, which can greatly improve the quality of logistics packaging. High-quality printing results help enhance product and corporate image, and increase consumers' awareness and trust in the product. Therefore, a carton printing paper feeding device with a wrench-free paper feeding roller adjustment is proposed.

[0003] The existing Chinese utility model patent with publication number CN214324318U discloses a paper feeding device for carton printing, belonging to the field of carton printing technology. This technical solution includes two sets of fixed support frames placed opposite each other. A mounting side plate is fixedly connected to the top of each fixed support frame. A drive motor is located on one side of each mounting side plate near both ends. Rolling wheels are movably connected between the two sets of mounting side plates via bearings. Each rolling wheel includes a driving wheel and a driven wheel. A transmission wheel is fixedly connected to the right end of the driving wheel, located outside the mounting side plate. The left ends of the rolling wheels near both ends of the mounting side plate are fixedly connected to the output ends of the drive motors. A support frame plate is fixedly connected to the top of each mounting side plate, and a sliding seat is provided on the side of the support frame plate. This utility model, by setting up a roller structure for driving the carton to move, and by setting up a driving wheel and a driven wheel structure between the rolling wheels, avoids the situation where all driving wheels can easily cause the carton to get stuck on the inside.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that since paper needs to be continuously fed into the carton during printing, inconsistent paper feeding speeds can occur, leading to paper jams and malfunctions. Furthermore, the printing press has a large overall structure, making it difficult to disassemble and repair. All these problems affect the use of the device. Utility Model Content
